error: cannot apply unary operator ! to type `collections::vec::Vec<int> (compiler error) #19259
Description
Seems like I caused this by passing two arguments to assert!, mistaking it for assert_eq!. Also seems to be related to one of them being a vector.
The specific line that blew everything up:
assert!(slide_iter.next().unwrap(), vec![1, 2, 3, 4, 5])Version:
